Photos include some "Budget Brand" racing header cut-away shots, for quality comparison to these top quality A-1 Performance Headers. A little more money for an A-1 gets you a LOT nicer header for your VW!

A-1 Performance Sidewinder HT Merged Racing HEADER (Muffler Nor J-pipes included), for Flanged J-Pipes (Heater Box Compatible), Mid Size Tubing offers the best balance of performance, looks, and ground clearance, of any VW Performance Exhaust available! Each one is hand made by a master exhaust system craftsman for YOUR car! Remember that Exhaust Tubing is measured on the OUTSIDE (Not Inside), stock is equivalent to 1 1/4" tubing. A decent guideline is to run 1 3/8" for up to 90hp, 1 1/2" from 90-140hp, and 1 5/8" from 140-175hp. Above this you need a larger exhaust tubing, which we do offer but they cost more! These headers feature a 1 7/8" collector, which is sized properly for engines using up to 1 5/8" primaries. Many other brands of headers have a collector which is too big, and this results in a loss of power and a lot of tuning headaches!

Cylinder 1 and 3 J-pipes or Heater Boxes are not included with this header and must be purchased separately!

A-1 Racing Headers are designed with a silky smooth 'Superflo' merged collector (see the cut-away comparison photos), and offer dyno-proven performance. The maximum ground clearance these headers have is icing on the cake! Equal length (tuned) mandrel bent tubing delivers TOP HP and torque at all RPMs. These are not the Chinese made "headers" (term used very loosely) that won't even bolt up to your engine (and when they do, they are lop-sided!)! Check out the examples of typical "Cheap" headers in the collector cut away photos so you know exactly what you are avoiding!

A-1's headers are hand-built with Heavy Duty 16 gauge steel tubing, not that paper thin junk! Are you sick of flanges that are warped out of the box, or that bend during normal exhaust tightening? End THAT once and for all with these Double Thick Tru Flat 3/8" head and collector flanges that are so straight you don't even need gaskets if you don't want to use them!

Once you've decided on the A-1 Performance Header and muffler that is right for you, don't forget to check out the related products below for compatible A-1 products to build the ultimate exhaust system for your ride!

Choose Exhaust Finish / Coating

Ceramic Coating is a life EXTENDER, not a lifetime coating. In other words, you should expect the coating to make the pipes last longer than normal but don't expect the coating to be shiny or to last forever. Normal lifespan varies according to where you live and if you drive the car in the winter in the salt zones. Salt zone, daily driver summer and winter the systems should last about 4 to 5 years normally.

Choose Collector Flange

The V-band Clamp Collector Flange option is a single Band-Clamp that holds the stinger or muffler to the header's collector. It's smaller and cleaner looking, and much faster to connect and disconnect, than the traditional 3-bolt collectors. YOU MUST ADD THE V-BAND OPTION TO BOTH YOUR MUFFLER AND HEADER TO GET A COMPLETE V-BAND SYSTEM. The upgrade fee of $60 is ONLY for one side.

O2 Sensor Options

O2 sensor is useful for Wideband Tuning, or for Closed Loop FI functionality. The Single O2 Sensor Option places an O2 bung in the collector at the 9 o'clock position. The O2 Sensor x 4 Option allows for individual cylinder monitoring.
